Federal American 5.56 NATO ammunition is loaded to military specification. This particular load uses the SS109 bullet, which is a 62-grain green tip M855 full metal jacket for highly retained velocity and accuracy at long range. Though not classified as armor piercing, the steel tip does penetrate farther than other types of ammo.

The 5.56 cartridge is covered by a layer of copper to protect your rifle barrel. The finished rounds consist of sealed primers for long term storage and moisture protection.

Federal American 5.56 NATO ammunition is ideal for use in M16A2 and M4 rifles. Please note military grade 5.56mm NATO rounds create a higher pressure than their .223 counterpart and are not designed to be fired in a .223 Remington chamber.
